Barbie's On the Go PAK sheath was available on the market from 1964-1965 in a floral print or in cherry red, rust, forest green, olive green, or blue with white mini-dots. The hardest sheath to find is the floral pattern. In 1962 and 1963 this PAK was issued only in the red, green, and blue shades and was titled simply, "sheath with gold buttons". The sheath was cotton and is the same pattern that was used in Barbie's Sheath Sensation fashion. There are four gold-tone buttons, 2 front pockets, and it ties in the back with snaps.
